Patented June 19, 1951 TERMINAL FOR WRISTBANDS FOR WATCHES Alfred Pinson, Fairfield County, Conn., assignor to Apex Accessories (30., Inc., Greenwich, Conn.

Application November 5, 1949, Serial No. 125,707

6 Claims.

My invention relates to terminals for wrist bands for watches, and the object thereof is to provide a. terminal that will secure to a band a Watch provided with rings or eyelets for attachment.

Another object of the invention is to provide the band terminal with a spring latched pin for engaging thering or eyelet of the watch to be attached.

A further object of the invention is to provide terminals for wrist band ends the construction of which harmonizes with the wrist band of which they form a part.

This particular type of terminal is mainly intended for bands to secure ladies wrist watches,

and it is particularly designed for the type of band disclosed in my application Serial No. 99,931, filed June 18,1949, for an expanding chain.

In the appended drawing forming part of this application:

Figure 1 is a section on line 1-5, Figure 2,

Figure 5 is an edge elevation of a modified spring latch.

Referring to the drawings:

Liners 5 of the terminal end are spaced laterally by the proximate end of a liner 6 of the expanding chain and are connected with their proximate ends to the proximate end of the liner 6 by a spring actuated toggle joint formed of links I having a common pivot 8 in the said proximate end of liner 6. The tendency of the spring actuated toggle joint is to draw the liners 5 towards the liner 6, which liner 6 is median with respect to the liners 5. The helical springs 9 which actuate the toggle joint formed by the links l are each housed in a corresponding eyelet H3 forming the pivot for the link with the corresponding liner and located in the ends of liners 5, which are proximate to the end of liner 6 therebetween. Each end 2? of the spring ii above the corresponding liner 5 is anchored by a hook-shaped abutment ll rising from the liner 5. The lower end 23 of each spring, shown in full lines in Figs. 1 and 4, by braking out portions of corresponding link i where it abuts against the side of the corresponding cover it,

better shown in Figures 3 and 4.

A yoke 13 is mounted at the other end of each liner 5 to swivel thereon on a rivet Hi, the axis of which rivet is substantially perpendicular to the surface of the liner on which it is mounted. A pin l5, preferably bowed in the middle, is anchored with one of its ends to one of the Yokes to move therewith, see lower liner 5 in Figure 1, while the other end of the pin is made to engage slidably the yoke 13 in the upper liner 5. To facilitate the sliding engagement of the unconnected end of the pin, with the yoke it thereof; the faces of the yoke which first come in contact with the end of the pin for engaging the same are flared out, as shown best at It in Figure 3.

The portion of the free end of the pin that is positioned between the sides 17 of the upper yoke It in Figure 1 when fully engaged therein is provided with a traverse slot l8 for receiving the movable end I9 of a spring latch 26 anchored with its other end 2| by the eyelet Iii. The spring latch 26 is provided with a hump 22 between the ends thereof projecting through an aperture 23 formed in the liner 5'. It will be noted from Figure 3 that the major portion of the liner 5 extending from the yoke is raised with reference to that portion where the yoke is mounted on the liner. This projection of the hump 22 of the spring latch through the upper liner 5 of Figures 1 and 4 permits the movement of the spring latch to the position indicated in dash and dot lines in Figure 3, which movement brings the end IQ of the latch out of the slot ll} of the pin and permits the removal of the pin 15' from the yoke l3 where the latch end l9 is'located, as indicated in dash and dot lines in Figure 1 and in full lines in Figure 4.

The movement of the liners 5 through the links i on the pivot 8 to the position .of the liners 5. indicated indash and dot lines in Figure 1 causes the pin !5 to swivel with its lower yoke 13 on the liner 5 to which it is connected, causing in turn the upper yoke iii to swivel to permit the'free end of the pin I5 to slide out from said upper yoke l3, bringing the free end of the pin out of the upper yoke see Figure l. Thefree-end of the pin can then be engaged by an eyelet or ring of a watch, and the liners 5 can be restored to their normal position by bring ing the free end of pin l5 into engagement with the upper yoke I3 where the spring latch 29 is provided.

It is evident that it will be necessary to raise the latch from between the sides 11 of the upper yoke l3 to permit the free end of the pin to engage the said yoke. The flares I 6 in the faces of the sides I! of the upper yoke l3 facilitate the engagement of the free end of the pin 15 with the openings in the sides I! for the pin IS in the upper yoke l3.

The liners are each provided with a domed cover in the form of a shell 2 each shell having an opening 25 large enough to be threaded easily on the pin when it is to be secured to the corresponding liner 5 to cover the parts mounted on the liner with the exception of the part of the pin extending between the liners 5 that pass through said openings 25.

In lieu of the spring latch 20 described, a flat spring latch 26, that is to say, one without a hump, may be substituted and operated through the opening 23 in the liner by any suitable tool that may be passed therethrough to engage the latch 25.

I claim:

1. A watch band terminal comprising a pair of laterally spaced elongated liners, a spring actuated toggle joint connecting the proximate ends of the liners to a band member median with respect to the liners, said toggle joint normally tending to draw the liners to said member, a pin mounted to swivel at the end of one of the liners remote from the end connected to the toggle, said pin being adapted to swivel in a plane substantially parallel to the liner to which it is connected, swiveling means on the other liner adapted to be engaged by the end of the pin, a spring actuated latch carried by said other liner to lock the pin to the means, and a dome-shaped cover for each liner over the parts mounted thereon.
